HVAC Expansion Valves

HVAC expansion valves regulate the flow of refrigerant in heat pumps. It is an important component of the system because it helps to maintain the proper balance of refrigerant, which is essential for the efficient operation of the heat pump.

Expansion valves come in a variety of designs, such as thermostatic, pressure-controlled, and float-type. The core purpose of each type, however slightly varied in how it controls the refrigerant flow, remains the same. 

The expansion valve in a heat pump system is often placed between the evaporator and the compressor. Its primary function is to control the flow of refrigerant as it transitions from a low-pressure, low-temperature state in the evaporator to a high-pressure, high-temperature state in the compressor. By regulating the flow of refrigerant, the expansion valve helps to ensure that the heat pump operates efficiently and effectively.

Keeping a heat pump's HVAC expansion valve in good working condition is crucial for its overall health and performance. Check the valve regularly for signs of wear and damage, and service or replace it as needed to maintain its functionality.
